ELECTRICAL CONTRACTOR recently published an article, written by Craig DiLouie, LC, defining a new dimension of lighting control–white light color tuning. Check it out here.
Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy Solid-state lighting has proven that it can deliver high-quality light with substantial energy savings in many applications. But dimming can still be an issue, as CALiPER testing and GATEWAY demonstrations have shown. This concern was […]
ARCHITECTURAL LIGHTING recently published an article about flicker with LED lighting, particularly problematic in some dimming scenarios. Click here to read it.
The U.S. Department of Energy (DOE) has published a new report, Dimming LEDs with Phase-Cut Dimmers: The Specifier’s Process for Maximizing Success. The report was created in response to issues raised about dimming by energy efficiency organizations and specifiers, and is based on experience from CALiPER testing and GATEWAY demonstrations. While progress has been made […]
The Alliance for Solid-State Illumination Systems and Technologies (ASSIST), a program of the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, recently released a new publication that addresses the issue of how lamps should dim in terms of their “look and feel” during the dimming process. The publication, ASSIST recommends… Dimming: A Technology-neutral Definition, provides […]
In 2012, University of California-Davis upgraded its exterior lighting as part of its Smart Lighting Initiative. Wall packs on campus, like other exterior luminaires, were retrofitted with dimmable LED sources, motion sensors and wireless controls. This allowed the units to be incorporated into an adaptive campus-wide lighting control system. The system offers an intelligent, networked […]
Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy The U.S. Department of Energy (DOE) recently released a GATEWAY report on a parking-garage demonstration conducted at U.S. Department of Labor (DOL) headquarters in Washington, DC, which serves as a classic illustration of the savings […]
The Lighting Controls Association is pleased to announce that EE300: Lighting Control of LEDs, one of the Association’s popular online Education Express distance education courses, has been completely revised. Residing here, Education Express provides in-depth education about lighting control and controllable ballast technology, application, system design and commissioning, as well as meta-issues such as commissioning, […]
Intelligent, controllable LED lamps offer a new paradigm for home lighting control. Julie Jacobson, editor of ELECTRONIC HOUSE, analyzes the pros and cons of 13 products implementing WiFi/Internet of Things, 6LoWPAN, ZigBee, Z-Wave and Bluetooth. Read it here.
At the Department of Energy’s 10th Annual SSL R&D Workshop in Long Beach, California, nearly 250 attendees discussed the next great leap forward in performance of LED systems. In his February 8, 2013 SSL Postings, “Some Thoughts on the Long Beach R&D Workshop,” DOE SSL Program Manager Jim Brodrick related an interesting statement by Susanne […]
